When the first Kublai series chassis was introduced in 2007, it had innovative storage design that was ahead of its time. For the Kublai KL04, SilverStone engineers again looked to raise the bar with a design that can accommodate four 5.25” drive bays, nine 3.5” hard drives, and up to six 2.5” SSDs. This astonishing amount of storage capacity for a mid-tower chassis is unprecedented and comes with no compromise to compatibility. Expansion cards or graphics cards up to 17 inches long can be installed without the need to remove hard drive cage and even with all hard drive bays filled, cards up to 12.8 inches can still be used. To cope with densely packed hard drive bays, repeated thermal tests and revisions were made to come up with an airflow layout that is capable of handling all hard drives installed without negatively affecting the rest of the system. The right front positioning of the intake fans also helps to divert noise from leaking out directly to the front of the chassis. For 2.5” SSD or HDD mountings, the KL04 has specially designed cages that can be mounted in two locations depending on user needs. If you are looking for a chassis with server-like room for expansion but only limited footprint for a mid-tower, the KL04 is the choice.

*1 – If bottom fan or 2.5” SSD is installed, the maximum depth for PSU is 180mm (or 160mm with extra cabling room), otherwise there are no depth limitations.
*2 – If hard drive is installed in front of the cards, the length limitation is 12.8 inches.

Q. When I fill up the drive cage with hard drives, it looks cramped with no ventilation, would this cause problems?

A: The KL04 has a unique 5cm spacing designed between the drive cage and the intake fan, which enables cool air to flow directly onto
installed hard drive’s aluminum surface. This design has been validated by SilverStone’s R&D team through repeated thermal testing
to be fully capable in coping with fully installed cage.
The extra 5cm spacing also allows KL04’s graphics card cooling to be unaffected by the number of hard drives installed.

Q. Where should I place my PC for lower noise?

A: The hard drive fan and hard drive noises can leak out through the right
intake vents so we recommend placing your PC to your right side to turn
away the noise source.

Q. What can I do with the extra space to the right of the power supply
compartment?

A: The extra space there is designed for cable storage. If you are using a
non-modular power supply, you can store extra cables there. Even if you
use modular power supply, you can still store unused cables in the extra
space to avoid misplacing them.

Q. Where can I install a dual radiator (2 x 120mm)?

A: You may install the radiator where the top fan is located. Since installing the radiator there will interfere with a large CPU air cooler,
the radiator must be used for CPU cooling.

Q. Why are hard drives installed upside down?

A: This is to avoid hard drive’s connected SATA cables interfering with long graphics cards.
